Description

  The present invention relates to an information processing apparatus and a wireless input apparatus authentication method.

  In the technology of information processing devices such as personal computers, wireless input devices such as wireless keyboards and wireless mice are being used because connection lines to the main body are unnecessary and can be operated from a free position within a certain distance. The wireless input device of such an information processing device may be operated from another wireless input device that is not permitted to be used, and it is desired to check the wireless input device.

  An example of a conventional authentication method related to a wireless keyboard (see Patent Document 1) will be described with reference to an explanatory diagram of a conventional example shown in FIG.

  In FIG. 4, 60 is a wireless keyboard, 61 is a CPU, 62 is an internal memory composed of a nonvolatile memory, 63 is an external memory composed of a readable / writable nonvolatile memory, 64 is a key matrix, and 65 is a radio frequency. A block 66 is an antenna.

In FIG. 4, when the wireless keyboard 60 is shipped, an initial identification code is recorded in the internal memory 62 and a flag (for causing the CPU 61 to recognize the initial identification code) is recorded in the external memory 63. An initial identification code is also registered in the receiver. After shipment, the user performs authentication using the initial identification code (the initial identification code is transmitted from the wireless keyboard 60 to the receiver and matches the initial identification code registered in the receiver), and the wireless keyboard 60 Is ready to use immediately. When using a plurality of systems, interference occurs between a plurality of wireless keyboards. When the user records a new unique identification code in the external memory 63 in order to avoid the interference, the flag is erased and the receiver (computer) is further deleted. The unique identification code is registered. When the flag is erased, the CPU 61 transmits the new unique identification code in the external memory 63 as an identification code to the receiver.
